Structured data is easy to store, query, and analyze using standard tools and methods. For example, a customer database can store structured data such as names, addresses, phone numbers, and purchase history of each customer.

2. unstructured data: This is data that has no fixed or regular structure, such as text, images, audio, video, or social media posts. Unstructured data is more difficult to store, process, and analyze, as it requires specialized tools and techniques to extract meaningful information. For example, a customer feedback survey can collect unstructured data such as comments, ratings, and suggestions from each customer.

3. Semi-structured data: This is data that has some elements of structure, but not enough to fit into a rigid schema, such as JSON, CSV, or HTML files. Semi-structured data is more flexible and adaptable than structured data, but also more complex and challenging to handle than unstructured data. For example, a web page can contain semi-structured data such as headings, paragraphs, links, and images, each with different attributes and values.

4. big data: This is data that is characterized by its high volume, velocity, variety, veracity, and value. big data is generated from various sources at a rapid rate, and often contains different types and formats of data. Big data is difficult to manage and analyze using traditional tools and methods, as it requires advanced technologies and skills to deal with its complexity and scale. For example, a social media platform can produce big data from millions of users, posts, likes, shares, and interactions every day.

Some of the common data sources are:

1. Internal data sources: These are data sources that are generated or collected within your organization, such as operational data, transactional data, financial data, or employee data. Internal data sources are usually reliable and consistent, as they are subject to your organization's policies and standards. However, they may also be incomplete, outdated, or inaccurate, if they are not properly maintained and updated. For example, a sales report can provide internal data on the revenue, costs, and profits of each product or service.

2. external data sources: These are data sources that are obtained or acquired from outside your organization, such as market data, customer data, competitor data, or industry data. External data sources can provide valuable insights and opportunities for your business, as they can help you understand your customers, competitors, and industry better. However, they may also be unreliable, inconsistent, or irrelevant, if they are not verified and validated. For example, a customer review site can provide external data on the feedback, ratings, and preferences of your potential customers.

3. Public data sources: These are data sources that are available to the public, such as government data, academic data, or open data. Public data sources can offer a wealth of information and knowledge for your business, as they can cover a wide range of topics and domains. However, they may also be outdated, incomplete, or inaccurate, if they are not regularly updated and maintained. For example, a census data set can provide public data on the demographics, income, and education of the population.

Data ethics principles and practices provide the norms and values for ensuring data integrity and responsibility, as well as respecting the rights and interests of the data subjects and stakeholders. Data managers should promote and adhere to data ethics principles and practices by following the relevant data laws and regulations, such as the General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA), and the Health Insurance Portability and Accountability Act (HIPAA). Data managers should also follow the best practices and guidelines from the data industry and community, such as the Association for Computing Machinery (ACM) Code of Ethics and Professional Conduct, the Data Ethics Framework from the UK Government, and the Data Ethics Canvas from the Open Data Institute. For example, data managers should ensure that data is collected, processed, analyzed, and used in a lawful, fair, transparent, accountable, and beneficial manner, and that data subjects and stakeholders are informed, consented, and empowered regarding their data rights and choices.
